CASTER FOR FURNITURE.

$pecification of Letters Patent." Patented Sept. 1 1909.

Application health 2, 1908. Serial No. 441,593.

To all whom it may concern:

Be it known that l, GEORGE E. NEUBERTH, u citizen of the United States, residing at Newark, cw Jersey, have invented certain new and useful Improvements in Casters for Furniture, of which the following is n specification, last: 20,) illustrated by drawings.

The invention relates particularly to casters for pianos and other heavy furniture, but its applicability is by no means limited thereto.

it relates particularly to the inznnier of securing the custer pinlle so that it may turn in bearings und hesccu'rely supported relatively tothe by u structure that is economic-.11 to manufacture.

The invention und its viii-ions parts will be readily understood from the following description and claims. o

in the drzuvings, Figure 1 is an elevat on partly incentrul section through the leg, showing a caster embodying the invention and applied, to a piano leg. Fig. 2 is a detail vertical sectional view of portions of the some caster. Figs. 3, 4-, and 5 are respectively :1 bottom view, a section on the plane.

si 4'. and a plan view of the flange member shown in Figs. 1 and 2. Fig. 6 is a. detail view partly in section, showing a modification.

In the preferred embodil'nents shown in Figs. 1 to 5 inclusive the caster Wheel V, jun's J, pintlc P, and disk or flange D screwed or otherwise secured to the leg are illustrated in at well known form which it is unnecessary further to describe. The disk I) may carry the weight of the leg onto the enlarged jJUifiiOll of the pintlc, as illustrated. "the j ournzils or bearings for the pintle P are furnished by :1 tubular portion or member T which, for eu'rononiy of manufacture, may be made of sheet metal. with an open longitudinal scam f. \Vhcthcr seamless or having such an open seznn f, the socket or hearing T is closely embraced and externally supported by the disk l and is preferably turned over or upset on either .ince of the disk, :is in Fig.

it should pre'lcrulny externally fit and be supported by the lower end of the hole or here B in the leg, as is well understood.

My im provement particularly concerns the upper portions of the ouster, which in the most perfect form of the invention is reinforced on the exterior of the socket or bearing T by a flange member F formed of sheet metal and crimped down so as to firmly embrace and externally strengthen and support the upper end of the tubular socket T, and which is provided with several externally projecting bends or folds f of the down-turned flange that closely fit'and derive external support from the wall of the bore B in the leg, as seen in Fig. 1. I prefer also thatthe upper end of the )intle P projectthrough the flange member and be riveted over or headed up above it so as to hold the pintle to the socket, and furthermore, that the hole in the flangemember be of the same diameter as the internal diam eter of the upper. end of the socket, so that both may jointly 'form a journal bearing for the upper end of the pintle. The tubular socket T is shown reduced slightly at its up-- per portion to form an approximately accurate bearing for the pintle, as at t, and of full size at t" where 1t is secured to thedisk D and forms the lower journal bearing for a larger diameter of the pintle P. The flange member F in the form illustrated constitutes a cap which is preferably completed before it is placed upon the upper end of the tubular socket and fits the same so tightly that it has to be jammed or forced thereon with considerable pressure so as t0 produce a very strong and well supported upper bearing for the pintle.

In the modification shown in Fig. 6 the flange member is impcrforate, the intle P being first upset or headed to hold it to the tubular socket T and then the flange mom-- her F is put on and forms a complete cap inclosing the head of the pintle and embracing the end of the tubular socket T.

In the operation of the invention as embodied in the caster above described, the bore ll of proper size is formed in the leg and the socket is thrust into place in the bore, the portions f fitting the bore, the disk D being then screwed to the leg. The pintle free to turn and is very firmly and so; curely supported in such a Way that the tubular socket is subjected to very slight disrupting stresses and a very strong, durable, easily constructed and easily applied construction is assured even though very-lightsheet metal be used in the socket or bear ng.

The invention is, of course, not necessarily the parts I claim the following;

embracing and externally supporting the tubular socket. or bearing and adapted to fit and be supported in turn by the bore of theleg with which the caster is used, the

upperend of the pintle projecting through the said flange member and being secured to the socket thereby.

2. A caster having a pintle and a tubular socket or bearing therefor, distinguished by having at the upper end of the socket 0r lo jbe'aring a flange member projecting laterally of the socket, the flange of which extends downward upon the outside of the socket or bearing and embraces and su ports the same.

3. A caster having a pintl and a tubular 2o socket or bearing therefor, distinguished by having at the upper end of the socket or bearing aflange-member projecting laterally of the socket, the flange of which extends downward upon the outside of the socket or bearing and embraces and supports the same,

the pintle projecting through the said flange member and being enlarged so as to beheld by the said member. I

i 4. A caster having a pintle. and tubular ML socket therefor and a member, portions of which extend down in contact with the exterior of the said socket and thereby embrace and strengthen it,-said member also project ing laterally from'the socket to fit and be supported by the interior of the leg in which I the caster is used.

5. A caster having a pintle and tubular socket, av leg-supporting flange whlch embraces and strengthens the lower end of the 40 socket and which is provided with means for securing the socket to a leg, said caster also having an embracing men'iber which ex tends downward in contact with and cmbracing the upper portion of the socket, and

which projects laterally from the socket to lit the bore of a leg.

laterally from the socket socket therefor and a member embracing.

the upper portion of the tubular socket and hav1n a downwardl ex'ten'din crim ed or folded flange in contact with the exterior of the socket.

8. A caster having apintlc and a tubular socket or hearing for the ointle, distinguished by havinga winged flange member with downwardly exlcmfling portions for embracing and external] y supporting the tubular socket or bearing and projecting and therebyadapted to fit and be supported in turn by the bore of the leg with which the further distinguished by having a leg-supporting flange and means for securing such flange to the leg.

9. A caster having a pintle and a tubular socket or hearing for the pintle, distinguished by having a flange member with downwardly extending portions for embracmg socket or hearing and which project outward from the socket and. are adapted to lit and be supported in turn by the bore of the leg with which the caster is used, the upper end of the pintle projecting through the said flange member and being secured to the socket thereby, and further distinguished by having a leg-su 'ipoiting flange and means for securing such flange to the leg.

In testimony whereof I have signed this specification in the 'n'esence of two subscribing witnesses, June 30, 1908.
